Overview
The AP6015-33M10G-13 is a synchronous step-down DC-DC converter manufactured by Diodes Incorporated. It operates with an input voltage range of 2.5V to 5.5V and provides a fixed output voltage of 3.3V. The device supports up to 800mA output current with a typical quiescent current of 150μA. It features a 1MHz switching frequency, internal soft-start, and shutdown capability. Packaged in MSOP-10, it functions within a temperature range of -40°C to +85°C.
Feature Summary
- High efficiency synchronous step-down conversion exceeding 94% efficiency
- Current mode operation for improved transient response and loop stability
- Integrated internal soft-start function to limit inrush current
- RoHS compliant construction using green molding compound without bromine or antimony
Applications
- Mobile handsets
- PDAs and Ultra Mobile PCs
- Portable media players
- Digital still and video cameras
- USB-based DSL modems
Procurement Notes
Verify the specific suffix M10G-13 against the manufacturer datasheet to confirm package type and compliance status. Ensure the fixed 3.3V output variant matches the design requirement, as other fixed voltage options exist within the AP6015 family. Confirm RoHS compliance documentation is available for the specific batch.
Selection Notes
Select this component when a fixed 3.3V rail is required from a single-cell Li-ion or multi-cell battery source. The 800mA current capacity suits low-power portable applications. Consider the MSOP-10 package constraints for PCB layout. Verify that the 1MHz frequency aligns with EMI requirements and inductor size limitations.
Part Context
This part belongs to the AP6015 family of low-noise current mode synchronous step-down converters. It is designed for systems powered by 1-cell Li-ion or 2- to 3-cell NiCd/NiMH/Alkaline batteries. The family includes adjustable and fixed voltage variants, all sharing the same core topology and performance characteristics.
Replacement Considerations
Direct substitutes include other AP6015 fixed voltage variants such as AP6015-18M10G-13 (1.8V) or AP6015-25M10G-13 (2.5V) if the output voltage can be adjusted. Cross-referencing with similar synchronous buck regulators from other manufacturers requires verifying pin compatibility and electrical specifications.
